SAMUEL BUDD, 0F PHILADELPHIA, PENNSYLVANIA, AASSIGNOR TO HIMSELF AND HENRY BUDD, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 328,875, dated October 20, 1885.

Application led September 8, 1885. Serial No. 176,470,

To all whom it may concern:

Be it known that I, SAMUEL W. BUDD, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Latch-Locks, of which the following is a specification.

My invention consists of certain improvements in the construction of latch-locks, as fully described hereinafter.

In the accompanying drawings, Figure l is a face view of the lock with the inner coverplate removed. Fig. 2 is a sectional plan View on the line 3 4, Fig. l. Fig. 3 is a transverse section on the line l 2, Fig. l; and Fig. 4 is a perspective View of two parts of the lock detached.

A is the case of the lock, which may be of any suitable configuration, and provided with the usual openings, a, for the passage of the screws by which the lock is to be secured to the door. This case is provided with the usual detachable inner face-plate, B, Figs. 2 and 3, which has the usual key-hole, b.

D is the bolt of the lock, having a beveled nose, d, which, under the action of a spring, K, normally projects through a slot in the end of the case A, as shown in Figs. l and 2, the nose being guided in this slot. The rear end of the bolt is made in the form of a yoke, D, the cross-piece d of which is notched on the under side for the reception of a guide-iiange, e, on the inner face of the case A. The under side of the yoke D is provided with two pro` jections, f, to be acted on by the arms of a lever, F, which is secured to and carried by the stem g of the knob G, the latter being on the outside of the lock, while its stem projects through the case to the interior. Thelever Fis secured to the stem of the knob G in a manner which will be understood on reference to Figs. 3 and 4. The stem g of the knob is made tubular, and is inserted in a beveled opening, p, in the lever F, which beveled opening is provided with notches or projections p', and by means of a suitable tool the tubular end of the stem g is expanded outward, so as topractically rivet it to the lever F, as shown in Fig. 3. I utilize this opening in the end of the stem G as a seat for the stem of the key, as

(No model.)

illustrated in Fig. 3, the bit of the key engaging with a projection, o, on the lever F, to operate the latter and the bolt D.

The bolt D is provided with the usual projection, m, shown by dotted lines in Fig. 1, With which engages the retaining-catch M, loosely pivoted to a pin, a, on the inner face of the case A.

In order to prevent the catch M from jumping off its pivot-pin Without requiring any riveting, the yoke D is made of such a character asTto extend over the pivoted end of the catch M, as shown in Figs. 1 and 2.

Instead of having the usual curved spring to act on the catch-lever M, to hold the latter by friction in an'y position to which it may be moved, I provide the said catch-lever with a stem, s, carrying a spiral spring, S, the outer end of which bears against the inner faceplate, B, as shown in Fig. 2.

I claim as my inventionl. The combination of a bolt of a latch-lock with an operatinglever having an opening with notches or projections and a knob provided With a tubular stem adapted to the opening in thelever, substantially as described.

2. .The combination of the bolt and an operating-lever having an opening with a knob having a tubular stem adapted to the opening in the lever to secure the latter, the tubular portion of the said stem forming a seat for the key, substantially as described.

3. The combination of the bolt of a lock with a pivoted catch therefor, the said bolt having a yoke extending over the pivot of the catch to retain it in place, substantially as described.

4. The combination of the bolt ot" the lock and casin g therefor with a movable catch-lever, M, having a stem, s, provided with a spiral Afriction-spring, S, bearing against the face of the latter to retain the catch-lever in the positions to which it may be moved.

In testimony whereof I have signed my name `to this specification in the presence of two subscribing witnesses.
